COTTON-BAG EMPTIER.

Application filed August 10, 1915.

To all whom it may concern:

Be it known that I, Oois A. Brown, a citizen of the United states,residing at Santa Anna, in the county of Coleman and State of lexas,have invented new and useful Improvements in Cotton-Bag Emptiers, ofwhich the following is a specification.

This invention relates to cotton bag emptiers, and it has for its objectto produce a simple and efiicient device in the nature of a portablederrick, whereby bags that have been filled with cotton by the pickersmay be conveniently hoisted and their contents emptied into a wagon box,dispensing with the necessity of each picker climbing on the wagon boxfor the purpose of emptying his bag and thereby saving much valuabletime and strenuous labor which may otherwise be more profitablyemployed.

A further object of the invention is to produce a hoisting frame ofsimple and improved construction with which the bag may be convenientlyconnected for hoisting, means being provided whereby the top of the bagmay be released when the proper position has been reached, so as tocause the contents to be dumped.

A further object of the invention is to provide simple and improvedmeans whereby the derrick frame may be connected with a wagon box of anyheight, and whereby the derrick frame may be rotated and secured at theproper adjustment.

WVith these and other encs in view which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointed outin the claims.

In the accompanying drawings has been illustrated a simple and preferredform of the invention it being, however, understood'that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifictions within the scope of theclaims may be resorted to when desired.

In the drawings, Figure 1 is a perspective view of the derrick member ofthe improved device. Fig. 2 is a perspective detail view, enlarged, ofthe hoisting frame and related parts. Fig. 3 is a view in elevation ofthe hoisting frame having the bag connected therewith. Fig. 4 is a viewsimilar to Fig. 3, but showing the bag arranged for dis- Spccificationof Letters Patent.

charging its contents. Fig. 5 is a detail new of the bag.

Corresponding parts in the several figures are denoted by likecharacters of reference. Referring to the drawings, designates a derrickbeam having at its lower end a ground engaging flange 17 to engage thesurface of the ground so as to prevent the beam from entering into thesoil when the latter is soft. The beam 15 has at its upper end an arm 18which is reinforced by a brace 19. Said beam is also provided near itsupper end with a loosely fitting collar 20 with which are connected guyropes or wires 21, the lower ends of which are connected with stakes 22which may be readily driven in the ground for the purpose of sustainingthe derrick in position. Secured upon the derrick beam 15 at a properelevation above the ground by means of a clamp 23 is a lever 2-l bymeans of which the derrick beam may be rotated about its axis, saidlever having at its free end a hook 25. A sleeve 26 slidably engagingthe beam above the clamp 24, on which it normally rests, is providedwith arms or braces 27 pivotally connected therewith, said arms orbraces having terminal hooks 28 which may be equipped with set screws29, these hooks being adapted to engage the edges of the wagon box, notshown. These arms will not only serve to space the derrick beam properlyfrom the wagon, but will also materially assist in maintaining thederrick beam in an upright or vertical position for operation.

The arm 18 at the upper end of the den rick beam supports a pulley 31over which is guided a flexible hoisting element, such as a rope orcable 32, one end of which carries the hoisting frame H. The latter, asseen in. the drawing, consists of a triangular frame formed of a stoutmetallic rod or wire, said frame being provided at the apex thereof witha loop 33' for the attachment of the hoisting rope 32, and at each ofits lower corners with an eye 34 with which a hook 35 is connected. Thebase member 36 of the frame H supports a hook member 37 which is bentrearwardly therefrom and with which is pivotally connected, at 38, alever having an upwardly extending arm 39 and a downwardly extending arm40 with which latter a trip rope ll is connected. By the constructionshown the hook member is composed of spaced side members between whichthe arm 39 of the lever may swing when a cotton bag is mounted thereon,as seen in Fig. 8.

The cotton bag used in connection with this invention, a specimen ofwhich is shown at B, is provided at its lower corners with rings 12adapted to engage the hooks 35- supported at the lower corners of theframe I-I. Said bag is also provided with the usual shoulder strap orcarrying strap 43 which is incidentally connected with and supported bythe hook member 37 when the device is in use.

In the operation of this invention, the derrick member is erectedclosely adjacent to a wagon box which is driven to a convenient point inthe field. It is obvious that by raising or lowering the clamp 23 whichsupports the sleeve 26 having the brace arms 27, the device may beadjusted to operate in connection with a high or low wagon box, as maybe required. The pickers having filled their bags will carry them to thewagon box. To hoist a bag the strap 43 is engaged with the hook member37, and the lower corners of the bag are lifted, the rings 12 beingconnected with the hooks 35. During this part of the operation, thederrick beam is arranged with the arm 18 in parallel relation to theside of the wagon box. By pulling on the hoisting rope 21, the bag isnow hoisted to the requisite height, after which by laying hold of thelever 24, the derrick beam may be swung about its axis until the arm 18extends laterally above the wagon box, in which position it may besecured by engaging the hook 28 with one of the brace arms 27. Bypulling the trip rope t1, the strap 43 will now be disengaged from thehook 37, and the mouth of the bag will. swing downward, causing thecontents to be emptied into the wagon box, after which the derrick beammay be swung about its axis until the arm 18 assumes a positionsubstantially parallel to the side of the wagon box, when the frame Hand the bag connected therewith may be lowered and the operationrepeated.

It will be seen from the foregoing that I have devised a very simple andeffective construction and arrangement of parts whereby much of the hardand unprofitable labor in the cotton field may be dispensed with and thestrength of the pickers conserved for more useful purposes.

Having thus described the invention, what is claimed as new, is

1. In a device of the class described, a hoisting frame of triangularform having a loop at its apex, and eyes at the lower corners thereof, ahoisting element connected with the loop, and hooks supported by theeyes, the base member of said triangular frame being provided with ahook member bent rearwardly therefrom and comprising spaced sidemembers, and a stripping lever pivotally connected with the hook and havin an arm operating between the side members. V

2. In a device of the class described, a hoisting frame of triangularform provided at its lower corners with bag attaching means, said framebeing provided intermediate the lower cornersthereof with a hook memberand a pivotally supported stripping lever.

B. The combination with a cotton bag having a strap near the mouththereof, of a triangular hoisting frame and hoisting means for elevatingsaid frame, the latter being provided at the lower corners thereof withmeans to support the lower corners of the bag, and intermediate saidcorners with a hook for engagement with the strap, and means forstripping said strap from the hook.

In testimony whereof I aflix my signature in presence of two witnesses.
